Rooting desire firmware 1.23

Hi,
I updated my ROM to version 1.23.351 by using the RUU application
And the boot loader became version 8.0
I wanted to root the device but I read that rooting is only for version 1.21.x
So I decided to downgrade it by flashing it again with an older version 1.21
But I get an error saying something like "cannot upgrade because bootloader's current version is more resent" something in that meaning...
So I was wondering if I can just go ahead and use the same steps for rooting 1.23 that are wrtitten for version 1.21?
Thanks
Use unrevokedĀ³. No problem to root a Desire running bootloader 0.80.

[Q] Latest official ROM

Hi.
I'm looking for the latest RUU ROM (WWE or Europe) for our Desire S. I want to completely remove anything from phone and back to the factory state (after that official unlock and root).
Which version is the latest one?
Greetings.

The latest is ICS RUU 14.01.401.2
But the better way (that will keep your warranty, that is void by htcdev.com) will be:
S-OFF (downgrade without using htcdev if your current bootloader is 2.x or go straight to revolutionary.io if it is 0.98.x)
Change the bootloader to 7.xx and flash 4EXT recovery touch
Flash the ICS RUU (keeping your hboot and recovery) and root it
For each step there is a dedicated Guide that you can find in the Index thread
Good luck :good:
How to change bootloader to 7.xx (as you wrote) or ENG bootloader (as in index topic)?
Does flashing via official RUU ICS file will keep my S-OFF and 7.xx/eng bootloader?
Is the 7.xx bootloader same as ENG bootloader? Which one is better and why?

downloaded the RUU for my country but it gave me :
ERROR [191]: ROM IS NOT SUPPORTED
My current software version is : 1.20.720.1 ... android 2.3.3
It says it needs version 1.57.720.1 for HBOOT update.
I haven't got any OTA update ( I also checked manually) to update to 1.57 version.

I tried by running ruu_chacha_htc_asia_wwe_1.57.707.2........ google it and you will find the RUU. run the RUU in administrator mode and you might have to try 2-3 times. Not remembering exactly how many times have to run it, but finally could upgrade and could generate "Unlock_code.bin"
I used customs ROMS and the best I found was SuperOSR chacha 2.5
Today only I have managed to downgrade to 1.20.720.1 and successfully restore the indian RUU. So now my Chacha is back to factory. Locked again.
